Jewel
Jewel was the main cultivar grown in NC in the 1970’s and 80’s but was replaced when Streptomyces soil rot became widespread. It has blocky shaped roots and a high packout of No.1 roots. It is a prolific plant producer in beds. Planting in cool soil temperatures will cause bally roots. It does not handle flooding well. It stores and ships well. Not recommended where Streptomyces is present. Moist, smooth and sweet when baked.
